A search for 𝐸𝑟𝑦𝑠𝑖𝑝ℎ𝑒 𝑡ℎ𝑒𝑠𝑖𝑖 led me to its British stronghold in Oxfordshire, where I soon found it at Hartslock NR. This high-quality chalk grassland was also the site of my 4,000th species in the British Isles, a day shy of five months after my 3,000th and a couple of days before my 17th birthday.

Sadly there were no takers over the weekend for the freebie Macmillan Guide, so if anyone would like this copy of a still brilliant little guide, ping us a DM or message me here & we can sort it from there. It has a slight rip on the back cover, which I'll sellotape up for free too 😉

Saturday giveaway time! I picked a copy of the (still brilliant) Macmillan Guide to Bird Identification at Cley village fete & like the last time, I want to give this copy to a really keen young birder (18 or under). Drop me a DM - or reply here - & Lynnette will pick a name from a hat. #ukbirding

Garden moth-trap last night contained this pyralid. Looks to be a few vaguely similar options - ObsIdentify seems keen on Ancylosis oblitella, which looks feasible? Anyone feel confident enough to say? Might have to try giving it the chop.

Rambur's Pied Shieldbug (Tritomegas sexmaculata), nymphs on Black Horehound at Manningtree this afternoon, perhaps the most northerly record so far? Also, a Hudsonian Godwit (not pictured), a long-overdue world tick for me - will have to visit again at low tide though, to see a bit more activity!

Important for anyone who verifies records on citizenship science websites, not just the ornithologists. @dipteristsforum.bsky.social @royentsoc.bsky.social

Our new commentary rdcu.be/ftx6h in @natecoevo.nature.com written with folks from @inaturalist.bsky.social and @cornellbirds.bsky.social shows that use of AI to manipulate existing or create new wildlife images undermines the huge value of vast citizen science databases. 🌍🪰🪶 #Ornithology 🧵 1/10

I keep reading about how the Common House-fly (Musca domestica) is much less common than it used to be. Well it's currently pretty darned common in my house. If anyone wants to twitch it .... well, you can probably find your own to be honest.

Two Common House-fly pinned specimens - a male above and a female below.

Nothris verbascella is a micro-moth, presumed extinct in Britain til rediscovered in 2024 nr Norwich by Dave Jones. Has only taken me 2 years to (literally) get on my bike and travel the 3 miles to see it. Larvae feed in the cruddy base of Hoary Mullein. Must return to see the adult in a few months.

I don't twitch many birds these days, but this is one that has continued to elude me. So a quick dash to Suffolk .... only for it to depart whilst I was on the way. Pah. Nice evening wander around Walberswick though instead. First GG Bush-crickets of the year, alongside range of expected birds

Just arrived home after a late morning appointment and news of the Hudsonian Godwit at Minsmere broke. Managed to see it on west scrape before it flew to south - the first time we saw the underwing... 2 limosa Black-taileds too #ukbirding #suffolkbirding

Ochsenheimeria taurella is a moth I have seen a few times, always from suction sampling. This one SE Norfolk today. Widened scales on the antennae give it a distinctive look.

This wee fly would appear to be a new species for Britain. I think it's Tetanops sintenisi (family Ulidiidae). Seems to be an east European thing that's spread west and is now widespread in Netherlands. I've got four from a vane trap near Ipswich from May/Jun this year.

My second new moth for the hectad TM29 today, a Yellow-legged Clearwing in the garden which came to a lure. The lure was the one for Orange-tailed Clearwing, however, so not quite the target.

Species 8,618: Metalampra italica (Italian Bark Moth). Found inside the house before I even got down the stairs this morning, as easy a new species gets! Quite widespread in Norfolk now, but looks to be new for my 10km square backwater.

Humid night resulted in at least 300/100 moths in the garden trap, plus a load of additional taxa including this rather nice little new bug for me - never previously clocked its existence!

Species 8,613: Stelis odontopyga (Smooth-saddled Dark Bee). Male and female found on the Essex coast last week, and in working them out, have realised that a 2022 specimen of 'breviuscula' was actually also this. First recorded in Britain in 2017, still not many recs www.flickr.com/photos/63075...

Stelis odontopyga (Smooth-saddled Dark Bee)

Very similar to S. phaeoptera and not distinguishable in the field though it averages a little smaller. Under a microscope the female upper propoodeum will be seen to lack any punctures (see photo anc...

Your annual reminder that if you only know one bramble make it Rubus armeniacus Himalayan Giant, the only truly invasive non-native bramble. Discolores (chalk white on leaf undersides), orange-green stems with contrasting red prickles. Huge in all parts. Overtops native communities. #BrambleDuJour
